The present invention relates to a unit to be mounted inside a furnace shell and to afford a circuitous path for the products of combustion so as to attain the maximum ef- 5 iciency therefrom.

Another very important object of the invention resides in the provision of a unit of this nature which is simple in itsV construction, inexpensive to manufacture, easy to as- 0 semble and disassemble, thoroughly reliable in use, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description pro- 15 ceeds, the invention resides in certain novel 0 with a dome like top 6 and in one end having doors 7 and 8 over openings therein. A suitable burner 9 is disposed in the iirebox. Rising from one end of the top 6 of the firebox is a neck 10. A vertical flue pipe 11 has its lower end telescoped over the neck and its upper end is reduced as at 12. Numeral 14 denotes a top section, numeral 15 a bottom section and numerals 16 a plurality of intermediate sections. These sections 14, 15 and 16 form horizontal flue sections. The bottom section 15 rests on spacer blocks 17 on the top structure 6 and is provided at one end with a neck 18 rising therefrom while the other end has a riser extension 19. An intermediate portion 16 has one end resting on the riser extension 19 and at the other end is provided with a depending neck 2O extending into the neck 18 and at said one end is provided with a neck 21 rising therefrom to receive a neck of the neck section 16 immediately thereabove. Spacer blocks 23 are disposed between sections 16 opposite to theends having telescoped necks. There may be any` number ofthese sections 16. Thetop section 14 has at one end a depending neck 24 tele- 55 scoping in the rising neck 21 of the section 16 therebelow and at the other end is provided with the depending neck 25 telescoped over the reduced end 12 of the flue 11.v Tie bolts 27 extend through ears projecting laterally 60" from the top section 14 and the firebox 5 and secure the sections, the flue and rebox alto gether in a unit. On one side of the bottom section 15 at the end having the riser extension 19 there is a laterally extending outlet 65 flue pipe 30.

From the above detailed description it will be readily apparent that the heated air and products of combustion from the irebox 5 pass up through the bight or iue 11 and then 7 downwardly in a sort of zig-zag manner through the sections 14, 16 and 15 out through the pipe 30. In this way the air rising through a shell 31 of conventional structure over the unit is heated to the maximum extent and eliiciency.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplication since in actual practice it attains the features of advantage enumerated as desirable in the statement of the'invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

In a furnace unit of the class described, a're box having a neck rising from one end thereof, a flue engaged with said neck and rising therefrom, a top section having a pair of depending necks one telescopically associated with the upper end of the flue, a plurality of intermediate sections of hollow construction each having a rising neck at one end and a depending neck at the other end, 5 depending necks of some intermediate sections telescopically associated with rising necks of the other sections, the uppermost of the intermediate sections having its rising neck telescopically associated with the other 10 depending neck of the top section, spacer blocks between the sections at ends remote from the telescopically connected necks, a bottom hollow section having an upwardly extending enlargement at its rear forming a 15 seat for the rear end of the lower intermediete section andl provided with a rising neck to receive telescopically the depending neck of said lowermost 'intermediate section, spacer blocks between the bottom section and the re 29' box, said rear enlargement in the bottom section having an .outlet opening in one side thereof, ears projecting laterally from the top sectonand the fire box, and tie bolts engaged therewith.
